To all whom t may concern Be it known that I, HORACE E. I-InNwooD,

"a subject of the King of Great Britain, re-

lene-Gas-Generator-Feeding Mechanism, of which the followin-g is a clear, full, and

exact description.

This invention relates to an acetylene gas generator of the general type described in a co-pending application of mine, executed of even date herewith, and originally filed February 1, 1912, Serial No. 674,648.

' The object of this invention is to provide another and specially advantageous type of u feeding device for securing substantially l absolute uniformity tuations of the light.

of feed to prevent fluc- In carrying'outmy invention, I preferably provide a head for my generator which may bel used to iill the same with carbid, and I attach it by means of a flexible diaphragm to the carbid receptacle sov as to have a vertical movement, its position dependingupon the pressure in the chamber, substantially as appears in my said other of the carbid.

application. A spindle connected with this head carries a feeding plug at its end, which passes through an aperture in the bottom of the carbid receptacle. This feeding plug `may be of any proper 'shape and have any kind of convolutions or projections thereon as may be desired, but to insure an accurate feed of the carbid in proper proportion to.

the consumption of gas and to prevent iiuctuation, I provide mechanism to permit this plug to be lowered through the aperture to give a greater or lesser size of opening for the feed of the carbid, and at the same time twist and turn the The scope of my invention will be point-ed out in the claims. -I

4 is a section on line 4 4 Fig. 2. Fig. 5 v ,is a sdeelevation of the bushing and helical l plug to aid in the feed sleeve. Fig. 6 is a section on line 6 6 Fig. 2. Fig. 7 is a plan of the filling head with the closure cap removed.

As shown in the drawings, 1 is the water l chamber.

2 is the carbid receptacle.

3 is the iilling head.

4 are springs tendingat all times to hold which carbid may be inserted. The filling head 3 is fastened by means of a diaphragm 10 to an inturned rim 11 of the carbid receptacle 2. l

The carbid receptacle has a conical bottom 12 which is also the top of the water chamber 1, through which conical bottom pipes 13 lead the gas to a point near the apex of said conical bottom. A spindle 14 is secured to the filling head 3, so as to rise and fall with it, but to be free for rotation with relation to the filling head, and it is secured to the filling head by a bushing 15 and a threaded pin 16 having a groove 17 therein for engagement by a set screw 1S, so that the pin 16 and spindle 14 may rotate freely in the bushing 15, but partake of all vertical movements with it.

The lower` end of the spindle 14 carries a conical plug 19 having a cylindrical end 20 fitting an aperture in a bushing 21 secured tothe apex of the conical bottom of the carbid receptacle. This bushing 21 carries a sleeve 22 extending into the water chamber and provided with helically disposed strips 25 with open spaces therebetween. The conical plug 19 carries below its cylinder 20 a small diameter `plug 23, into the sides of which there project guide pins 24,

vwell as lowered. Of course upon the lowering of the plug 19 the carbid will pass through the spaces between the helical strips above the cylindrical Vpart 20. The plug 19 may be of any shape desired to pass through the opening in the bushing 21. I however, prefer to provide oblique rings thereon forming ribs 26 as will be apparent from examination of Fig. G.

In carrying out this invention, details of construction may be varied from those shown, and yet the essence of the invention be retained; some parts might be employed without others, and new features thereof might be combined with elements old in the art in diverse ways, although the herein` described type is regarded as embodying substantial improvements over such modifications.

As many changes could be made in the 'above construction, and many apparently widely different embodiments of the invention could be made witlicut departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted in an illustrative and not in a limiting sense.

It is furthermore rdesired to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Subject-matter shown but not claimed herein constitutes the subject-matter of claims in my (zo-pending applications, Serial Numbers 823,245 and 823,246 .filed March 7, 1914. Case Serial Number 823,245 contains claims generic to the disclosures of all three applications, and case Serial Number 823,246, contains claims which are generic with respect to the present application, though specic with reference to case Serial Number 823,245.

I claim as my invention:

1. In an acetylene generator, a water chamber, a carbid receptacle having a feed aperture in its bottom, a flexible diaphragm, a feed plug, a shaft connecting the feed plug with the diaphragm, whereby the feed plug is caused to move up and down in the aperture, and means for imparting a rotary movement to the feed plug in conjunction with its vertical movement. Y

2. In an acetylene gas generator, a water chamber, a super-posed carbid receptacleY having` a conical bottom provided witha feed aperture, a vertically movable head and a diaphragm connected with the head, a laterally open sleeve with helical guides cominunicating with the feed aperture, Va `feed plug in engagement with said helical guides, and a connection between the feed plug and Vhead whereby the plug moves vertically with the head and rotates independently thereof.

3. In an acetylene gas generator, a water chamber, a superposcd carbid receptacle having a conical bottom, a vertically mov able head and a diaphragm connecting it with the carbid receptacle, a bushing in the Y conical bottom of the carbid receptacle and having a feed aperture and a laterally Open sleeve with helical guides communicating Y withV said aperture, a feed plug in engagement with said helical guides, and a connection between the feed plug and head where by the plug moves vertically with the headV having an upwardly tapering portion broken* by irregularities.
